ASA SUTTEN FISK, OF BINGHAMTON, NEW YORK.

STOVE-HOOD VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 378,669, dated February 28, 1888.

Application filed March 21,1887.

To all whom it may concern:

Be it known that I, ASA SUTTEN FrsK, a citizen of the United States, and a resident of Binghamton, in the county ofBroome and State of New York, have invented certain new and useful Improvements in Stove-Hood Ventilators, 850.; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, which form a part of this specification, and in'which elevation of the same.

Figure l is a perspective view of my improved stove-hood ventilator. Fig. 2 is a rear Fig. 3 is a central vertical sectional view. Fig. 4 is a horizontal transverse sectional View, taken on line at m, Fig. 2; and Fig. 5 is a sectional detail view of the adjustable funnel-shaped mouth-piece and the sleeve of the same.

The same letters of reference indicate corresponding parts in all the figures.

My invention consists in certain new and usefulimprovements on the invention for which Letters Patent of the United States No. 310,398 were granted to me, hearing date of January 6, 1885, and my invention will be hereinafter fully described and claimed.

Referring to the several parts by letter, A indicates a cook-stove of ordinary construction, to which my invention is shown as applied.

B indicates the hood, the lower rear edge of which rests upon the stove at the back thereof, the sides of the hood being cut away on a curve, as shown, so that their lower ends are not one-half the width of their upper ends, and 0 indicates the shelf which rests upon and is bolted to the top of the hood, the sides and back of the hood being bent or inclined in a short distance from their top before they reach the shelf, the shelf being supported on and bolted to the top of the hood, where the said top is reduced by the inward curve of the sides and back, as shown and described. The hood is made in two halves or sections, and its rear vertical edges, a, are secured and bolted between the registering longitudinal edge flanges or outwardly-bent edges D of the lower length, I), of the stove-pipe, this length of the stovepipe being madein two longitudinal halves or Serial No. 231,706. (N 0 model.)

sections, D the edges of which are bent out to form the longitudinal flanges D D.

0 indicates the shelf, which, as described, is supported upon and bolted to the reduced top of the hood B,- and this shelf is formed with a central opening, 0, which is covered by a funnel, E, on the lower end of a pipe, E, which I shall call the ventilator-pipe, this ventilator-pipe inclining toward the stove-pipe as it goes up, for a length of thestove-pipe, or to a point near the ceiling of the room, where it communicates at its upper end with ashort auxiliary ventilating-pipe, F, which enters the stove-pipe at that point. In this short auxiliary pipe F fits and turns a sleeve, G, having an opening, G, in one side adapted to register with the opening H, through which the ventilator-pipe E communicates with the short auxiliary pipe F, and the outer end of this sleeve G is provided with a funnel, I, to which a small handle, I, is secured, by means of which the funnel and sleeve can be conveniently turned or adjusted, for the purpose hereinafter specified.

The outer end of the auxiliary pipe F is provided with a slide-valve, J, pivoted near one edge of the opening of the pipe F, so that when the valve J is turned back the mouth or inlet of the said pipe is left clear for the entrance of the smoke and foul air which may rise to the upper part of the room. This valve J is provided with a small handle, J, for convenience in adjusting it.

It will be seen that in operation the smoke, steam, coal, and other noxious gases will rise into the hood and be thrown by the inclined upper parts of the sides and back into the funnel E, and, passing up through the ventilator-pipe E, will pass into the stove-pipe through the short auxiliary pipe F, passing through the opening G of the sleeve G, when the said opening is turned to register with the opening H, and as the ventilator-pipe approaches the stove-pipe as it rises toward its upper end, and is in close proximity to the stove-pipe for its upper half, the object of this construction being that the draft in the stovepipe may assist the draft in the ventilatorpipe as the said ventilator-pipe approaches the heated stove-pipe, the air from the ventilatorpipe passing quickly into the stove-pipe.

The valve J in the funnel I, at the outer end ICO of the slightly-downwardlyinclined auxiliary pipe F, may be kept closed when the gases, &c., are passing through the ventilator-pipe into the stove-pipe, or may be opened at that time to draw thesmoke, 850., from the upper part of the room into the stove-pipe; and when there is no cooking being done on the top of the stove, and it is desired to retain all of the heat of the stove in the room, the sleeve G is turned for a quarter of a circle, and thus closes the inlet between the ventilator-pipe and the interior of the said sleeve, thus cutting off the draft through the ventilator-pipe. Vhen the draft is thus cut off through the ventilatorpipe, the valve J may be opened, when the smoke, &c., and foul air'in rising to the upper part of the room will enter and be drawn through the sleeve G into the stove-pipe, and thuseonducted out of the room. It will be seen that the upper ventilator-pipe may be opened to ventilate the upper part of the room, either when the main ventilator-pipe is in operation or when the same is closed, the

- two ventilating-pipes operating independently of one another, and either may be used when the other is not in use, or both may be used together.

L indicates an auxiliary lower ventilatingpipe, which communicates at its upper end with the stove-pipe at a point a little above the top of the stove, while its lower end extends down nearly to the floor, and is provided at its lower end with a funnel, L, and this pipe,with its flaring mouth, is adapted to draw up the cold and damp air which settles near the floor, and also the dust from that neighborhood, the draft of the stove-pipe drawing up the air and dust through the lower pipe, L, creating a draft through the same, while as the said pipe extends down close to the stove it is heated by the stove, and the draft through it thus assisted.

The length of pipe formed by the two sections D forms the lower or firstlength of the stove-pipe. The front half of the said length only may be used and a regular length of pipe employed, being held in position within the front section, D by means of bands N, which are bolted in position, as shown, by means of bolts passing through their ends. The edges of the halves or sections of the hood, and the flanges of the front section or half of the lower joint, D and small clips or pieces, d, are fastened to the lower ends and back of the hood on the outside of the same, as shown, to fasten the hood to the stove with bolts or screws.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be readily understood.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

l. The combination of a Ventilating stovehood formed of two sections, the inner vertical edges of which are upon diametrically-opposite sides of the lower section of the stove-pipe, a short section,D the edges of which are flanged, a shelf, and means, substantially as described, for securing the inner edges of the sections of the hood to the flanges upon the section D", and for securing the pipe in position, substantially as set forth.

2. The combination of the hood having the inwardly-inclined upper end, the shelf having the central opening, the stove-pipe, the main ventilating-pipe having the funnel at its lower end, the short auxiliary Ventilating-pipe connecting the upper end of the main ventilating pipe with the stove-pipe, and the movable sleeve having the side opening and the valve at its outer flaring or funnel-shaped end, substantially as set forth.

3. The combination of the hood, preferably formed in two sections and adapted to be secured upon the stove, and having the inwardlyinclined upper end, the shelf having the central opening, the lower length of pipe formed in two longitudinal sections with the edge flanges, the stove-pipe, the inclined main ventilating-pipe having the funnel at its lower end, the short auxiliary ventilating-pipe connecting the upper end of the main ventilatingpipe with the stove-pipe, the movable sleeve having the side opening and the valve at its outer funnel-shaped end, and the lower auxiliary ventilating pipe having the funnel-shaped lower end extending down within a short distance of thefloor, all substantially as and for the purpose herein set forth.

, In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

ASA SUTTEN FISK.
